Anything you can be incarcerated for, if found guilty, is a crime. 6 months incarceration is the penalty in the U.S. Statutes for coming across the border illegally for the first time. The sentence can get stiffer for repeated violations. Illegal aliens are, by definition, criminals.

And don’t forget that the fine for using a social security number fraudulently is VERY steep. If we enforced those laws already on the books by going after employers, there would be more than enough in the kitty to build a secure border.
